Abstract: AQUEOUS SOLUTION OR DISPERSION OF A STYRENE/MALEIC ANHYDRIDE COPOLYMER AND PROCESS           FOR THE PREPARATION THEREOF Abstract of the disclosure: After hydrolysis and partial neutralization, copoly-mers of styrene and maleic anhydride are soluble or dis-persible in water.  Suitable copolymers have a molar ratio of styrene to maleic anhydride in the range of from 1.5:1 to 6:1 and a molecular weight of from 500 to 80,000.  Hy-drolysis and neutralization are carried out in the presence of an inorganic neutralizing agent at a temperature of from 75 to 250°C, thus neutralizing from 1 to 50 percent of the carboxyl groups of the corresponding copolymer.  The copo-lymer solution or dispersion is suitable especially for stabilizing aqueous dispersions of inorganic or organic substances.

Abstract: ABSTRACT    A battery operated microcomputer controlled programmable circuit testing device.  Standard I/O/memory devices are connected to a microcompu-ter in such a manner as to treat the I/O ports of the I/O memory devices as programmable interfaces and to allow pin receptors in a socket to be indi-vidually programmed as inputs or outputs.  Double detent switches connected to testable inputs the microcomputer are used to scroll a roll table contain-ing names of devices which may be tested in either a forward or a reverse direction at two different speeds.  Compression of the roll table storage is provided by storing only data which differs from the previous element.  A power supply having a regulator featuring a series pass transistor connected as a common collector amplifier is shown.  The power supply is turned on and off by switching devices which control base current only to a transistor switch operating analog circuitry which controls the pass tramsistor.  Micro-computer control of the power supply and self latching embodiments are also shown.  The power supply shown herein can successfully regulate output vol-tages which differ from the raw DC input by no more than the saturation voltages of series pass transistor.

Abstract: POSITIONING SYSTEM                   Abstract of the Disclosure A method of, and apparatus for, positioning semi-conductor wafers for precision operations is provided.  As a first step, a distinctive portion of a first wafer is chosen.          The distinctiveness of the portion is verified by comparing, the distinctive portion to portions intermediate to the distinctive portion and disposed around the distinctive portion.  The distinctive portion is then compared with pro-gressive portions on the wafer along a particular axis to determine rotary deviations of the wafer from disposition along the particular axis.  Corrections are then made in the rotary disposition of the wafer in accordance with such comparisons.          The displacement of such distinctive portion from a starting position on the wafer is then determined.

Abstract: Case 3796 CAPACITIVE KEYSWITCH           WITH OVERTRAVEL MECHANISM ON MOVEABLE PLATE            Abstract of the Disclosure A capacitive keyswitch is formed with a fixed horizontal plate that is imbedded in a horizontal printed circuit board below an overslaying dielectric layer and a moveable cantilever mounted plate that is hinged to the printed circuit board so as to project upwardly at an acute angle. When a plunger is actuated, a portion of it presses down on an overtravel mechanism that is formed from the moveable plate which causes the moveable plate to assume approximately a parallel position with respect to fixed horizontal plate, thereby changing the capacitance of the switch and actuating the switch. The overtravel mechanism consists of a tab cut out of a bent-up portion of the moveable plate so that the tab is bent along an intersection line formed by the intersection of the plane or moveable plate and the plane of the bent-up section.

Abstract: ABSTRACT OF THE DISCLOSURE        Methods are disclosed for obtaining a preferred multi-component metallic oxide coating on the surface of a glass substrate by pryolytic coating techniques.  In a pyrolytic coating technique, a heat decomposable, non-homogeneous, dry powder mixture of organic based metallic salts is sprayed against the surface of the glass substrate while the surface is at a temperature in the range from 700°F (370°C) to 1200°F (650°C).  In accordance with the general teachings of this specification, the methods are initiated by selecting a preferred composition for the metallic oxide coating to be developed on the surface of the substrate.  Different spraying compositions under a single set of spraying conditions or a single spray composition under different sets of spraying conditions are applied to test substrates to develop test specimens.  The chemical composition of the coating developed on the test specimens is determined and the spraying composition or spraying conditions which produced the preferred composition is then selected for use in spraying commercial quantities of a glass substrate.
